Kumagai tries to create textures through applying different materials in his works. After a glass piece is completed, the appearance of the soil and metal is influenced by how light falls on the object. Changes occur each moment within a day. In a dark room, the character of soil becomes apparent and the object may look like earthenware. In the morning sun or the evening sun, the character of glass appears stronger, as if the object itself casts the light.
From Shun: “If you have one of my art pieces, I would like you to enjoy feeling the changes of time throughout the days and seasons from it.”
